About ZeroTier

Our mission is to directly connect the world’s devices and enable a new era of decentralized computing.

Our software automatically handles the complexities of networking across physical network boundaries, dealing with mobility, and unifying cloud and edge to free you to spend your time building your projects and running your business.

Our network virtualization technology delivers the power of enterprise software defined networking to every device, service, and application whether it’s located at the edge or in the cloud. With ZeroTier you can treat the entire planet like one data center or cloud region. It’s capable enough for large businesses with complex networking needs but easy enough that tens of thousands of regular people use it to do simple things like play games online or connect to their home PC from their mobile device.

Our software and SDKs help developers build distributed and decentralized applications that are both easier to create and pleasurable to use. We work to solve the hard technical problems underlying decentralized application development so you can deliver applications that offer a positive low-friction user experience while avoiding the cost, liability, and security/privacy impact of a large highly involved cloud presence.

ZeroTier is located in Irvine, California and was founded by Adam Ierymenko in 2015.

Our Story

2013 Redecentralize interview about ZeroTier

ZeroTier started life as an open source project by its founder Adam Ierymenko with the goal of helping people directly connect to their devices and applications to help (re-)decentralize the Internet. The video to the right is an early interview recorded two years before ZeroTier became a company.

Starting with its 2013 launch as a beta open source project, ZeroTier began gaining users at a compounding rate of 11-14% per month. This growth rate continues to this day. When the size of our user base is plotted on a logarithmic scale it presents an almost perfectly straight line, a remarkably consistent exponential growth rate.

In 2015 a group of angel investors helped ZeroTier transition from an open source project to a business. Since then we’ve continued to release and support our open source products while earning income from select large customers (via licensing and support) and steadily investing in the development of a deep set of capabilities and a value added service ecosystem we can use to continue to support ZeroTier’s development well into the future. In 2018 we experienced our first “cash flow positive” year, and 2019 looks to be our first year of profitability.

While we’ve earned the majority of our revenue by working with larger enterprises on complex enterprise networking needs, our company’s soul remains rooted in its original values of privacy, decentralization, and user empowerment. It turns out that many of the pressing problems of complexity management, security, and performance that are faced by large enterprises overlap quite significantly with core problems in the Internet decentralization space.
